Cygnus Underwater Heavy Duty Remote Probe with 4 ft. 6 in. Lead (2.25MHz) 13mm
All Cygnus probes have a protective membrane fitted in front of the probe face to protect it from damage during use on rough corroded surfaces. A thin film of membrane couplant sits between the membrane and the probe face to allow the ultrasound to pass through. The membrane also helps the probe face "mould” to uneven corroded surfaces aiding measurement.
